<h1>tomcat以服务启动以及单机多版本部署</h1>
<hr />
<h2>说明</h2>
<p>对于tomcat需要增加内存的方法，基本上国内大部分的资料都是修改<code>$CATALINA_HOME/bin/catalina.sh</code>这个文件，增加<code>JAVA_OPTS</code>参数，这种方法在升级tomcat时会直接替换掉<code>catalina.sh</code>文件，导致服务受影响，这里介绍一种新方法。  
</p>
<h2>方法介绍</h2>
<p>仔细阅读catalina.sh文件，我们会发现其中有这么几行脚本文件   
</p>
<pre><code>if [ -r &quot;$CATALINA_BASE/bin/setenv.sh&quot; ]; then
  . &quot;$CATALINA_BASE/bin/setenv.sh&quot;
elif [ -r &quot;$CATALINA_HOME/bin/setenv.sh&quot; ]; then    
  . &quot;$CATALINA_HOME/bin/setenv.sh&quot;
fi  
</code></pre>

<p>此脚本会加载了<code>setenv.sh</code>这个脚本文件,而在<code>$CATALINA_HOME/bin/</code>下是没有这个文件的，因此我们可以把变量都写在这个文件中。如下：</p>
<pre><code>#!/bin/bash
CATALINA_PID=$CATALINA_HOME/bin/CATALINA_PID
JAVA_OPTS=&quot;-Xms256m -Xmx256m -Xss1024K&quot;
JAVA_HOME=/usr/local/jdk1.7.0_65
CLASSPATH=$JAVA_HOME/lib/tools.jar:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/jre/lib/rt.jar
CATALINA_HOME=/usr/local/tomcat7.0.54
PATH=$PATH:$JAVA_HOME/bin

export JAVA_HOME PATH  CATALINA_HOME CLASSPATH   
</code></pre>

<p>这样在启动tomcat的时候就能直接找到所需的环境变量，这种方法也适用于在同一台机器部署不同版本的tomcat使用不同版本的jdk.</p>
<h2>以服务启动</h2>
<pre><code>ln -s $CATALINA_HOME/bin/catalina.sh /etc/init.d/tomcat
vi /etc/init.d/tomcat
#chkconfig:2345 55 25  //加入到 #！/bin/bash下
chkconfig --add tomcat
</code></pre>

<h2>启动及重启</h2>
<p>可以通过如下方式启动以及停止tomcat，具体可以通过<code>/etc/init.d/tomcat --help</code>查看，这里不再赘述。</p>
<pre><code>service tomcat start   
service tomcat stop   
service tomcat stop -force 
</code></pre>
